COMPOUND BELTING.

SIFCIFICATION forming part of Letters Patent No. 419,650, dated January21, 1890.

Application tiled April 25, 1889. Serial No. 308,593. (No model.)

To @ZZ whom t may con/cern.:

Be it known that we, WILLIAM C. EDGE and CHARLES EDGE, both of Newark,Essex county, New Jersey, have invented certain new and usefulImprovements in Compound Belting, of which the following is aspeciication.

This invention relates to the class of belting that is made of knittedwire, and it has for its object to produce afriction-surface on thewearing side of the belting.l

The invention consists in a knitted-wire belt having a facing ofperforated leather or other fabric on the wearing side interwoven withthe meshes of the belting, as will be more fully hereinafter set forth,and finally pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which- Figure l is a detail face view of aportion of a machine that is adapted to construct our improved compoundbelting, showing also the manner in which the leather is united with thewire of the belting. Fig. 2 isa crosssection on the plane of the line cc, Fig. 3, showing in detail the manner of interweaving the leatherfrictionfacing with the belting. Fig. 3 is a face view of a piece of thefinished belting. Fig. 4. is a similar view of the opposite side of thebelting. Fig. 5 is a vertical section on the plane of the line c c, Fig.3, and Fig. 6 is a similar view of amodication.

The wire fabric shown in the drawings consists, primarily, of rows ofcrimped wire A, having wide loops d and narrower loops b, as indicatedin Fig. l.

To construct a piece of fabric the narrow loops b of one row are passedthrough the wide loops a of another row, and then the projecting partsof the narrow loops b are spread or widened, so as-to form a wide loopand prevent said loop being withdrawn from the other. The loops are thenpressed down fiat.

The United States Patent to William C. Edge, No. 242,616, dated June 7,1881, shows a machine by which the above-described fabric can be made,as well as showing some of the fabric, to which patent we refer for amore detailed description for constructing the wire portion of ourcompound belting.

In Fig. l the letter D indicates the part of said machine that causesthe loops to be interlocked.

Our compound belting is composed of the wire fabric A A, interwoven withstrips or sheets B of leather or analogous material.

Vhen in this specification we mention leather for the friction-producingsurface, we wish to be understood as meaning any analogous substancethat will answer the purpose.

Our preferred mode of constructing the compound belting consists inusing narrow -strips B of leather, as clearly shown in Figs.

2 and 5, which strips are perforated with a series of holes d, throughwhich the narrow loops h of the crimped wires A are passed, so that theleather B shall come into the bottoms of the loops a. (See Fig. 2.) Thenarrow loops h of one row A are then passed through the side loops a ofanother row A and spread or widened, as before indicated, whereby thestrips B are held in position between the loops d b of two rows A.

By the above construction one side of the wire belting A A is faced withleather B, that is held in position by the meshes of the belting. Asshown in Fig. 5, one edge of each strip B is overlapped by thecontiguous edge of the next strip B.

Instead ofusing separate narrow strips B for the friction-surface acontin nous sheet B may be used, having rows of perforations at theproper distances apart to receive the loops h of the crimped rows A.

v By having the leather facing B a knittedwire belt may be used withgreat advantage in many instances, because the belt is prevented fromslipping on the pulleys, &c., on account of the friction between thefacing B Vand the pulley.

0f course it will be understood that we do not confine ourselves to theparticular kind of knitted-wire fabric herein shown, as

d that receive the loops b, substantially as herein shown and described.
